Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun's atmosphere, the corona.
On July 19, 2012, an eruption occurred on the sun that produced all three. A moderately powerful solar flare exploded on the sun's lower right hand limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays -- a phenomenon known as coronal rain.
Over the course of the next day, hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, themselves, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, which highlights material at a temperature of about 50,000 Kelvin. This plasma acts as a tracer, helping scientists watch the dance of magnetic fields on the sun, outlining the fields as it slowly falls back to the solar surface.
The footage in this video was collected by the Solar Dynamics Observatory's AIA instrument. SDO collected one frame every 12 seconds, and the movie plays at 30 frames per second, so each second in this video corresponds to 6 minutes of real time. The video covers 12:30 a.m. EDT to 10:00 p.m. EDT on July 19, 2012.

It’s always shining, always ablaze with light and energy that drive weather, biology and more. In addition to keeping life alive on Earth, the sun also sends out a constant flow of particles called the solar wind, and it occasionally erupts with giant clouds of solar material, called coronal mass ejections, or explosions of X-rays called solar flares. These events can rattle our space environment out to the very edges of our solar system. In space, NASA’s Solar Dynamics Observatory, or SDO, keeps an eye on our nearest star 24/7. SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video, we experience SDO images of the sun in unprecedented detail. Presented in ultra-high definition, the video presents the dance of the ultra-hot material on our life-giving star in extraordinary detail, offering an intimate view of the grand forces of the solar system.

MAJOR X-CLASS SOLARFLARE (UPDATED): On Sept. 6th at 1202 UT, sunspot AR2673 unleashed a major X9.3-class solar flare--the strongest solar flare in more than a decade. X-rays and UV radiation from the blast ionized the top of Earth's atmosphere, causing a strong shortwave radio blackout over Europe, Africa and the Atlantic Ocean. The explosion also produced a coronal mass ejection (CME) with an Earth-directed component. The CME will probably reach our planet on Sept. 8th, bringing with it a chance of G2- or G3-class geomagnetic storms.

From NASA's Scientific VisualizationStudio. Solar flares may seem like far-away events, but they can damage satellites and even ground-based technologies and power grids. Every 11 years, as the sun reaches its maximum activity they become bigger and more common, and that increases the chances that one will significantly affect Earth.
So what are these solar eruptions? A solar flare is basically an explosion on the surface of the sun ranging from minutes to hours in length. Large flares can release enough energy to power the entire United States for a million years. Flares happen when the powerful magnetic fields in and around the sun reconnect. They're usually associated with active regions, often seen as sunspots, where the magnetic fields are strongest.
Flares are classified according to their strength. The smallest ones are B-class, followed by C, M and X, the largest. Similar to the Richter scale for earthquakes, each letter represents a ten-fold increase in energy output. So an X is 10 times an M and 100 times a C. Within each letter class, there is a finer scale from 1 to 9. C-class flares are too weak to noticeably affect Earth.
M-class flares can cause brief radio blackouts at the poles and minor radiation storms that might endanger astronauts. It's the X-class flares that are the real juggernauts. Although X is the last letter, there are flares more than 10 times the power of an X1, so X-class flares can go higher than 9. The most powerful flare on record was in 2003, during the last solar maximum. It was so powerful that it overloaded the sensors measuring it. They cut out at X17, and the flare was later estimated to be about X45.
A powerful X-class flare like that can create long lasting radiation storms, which can harm satellites, and even give airline passengers flying near the poles small radiation doses. X flares also have the potential to create global transmission problems and worldwide blackouts.
The seriousness of an X-class flare pointed at Earth is why NASA and NOAA constantly monitor the sun. NASA's Heliophysics fleet of spacecraft can now see the sun from every side and in many different wavelengths. This unprecedented coverage is enabling scientists to predict and detect space weather events like flares and CMEs with ever greater accuracy. With advance warning, governments and companies can take steps to protect their technological infrastructure, so that the worst scenarios will never happen.

These phenomena are generated by a helical dynamo near the center of the Sun's mass that generates strong magnetic fields and a chaotic dynamo near the surface that generates smaller magnetic field fluctuations.

Solar flare

A solar flare is a sudden flash of brightness observed near the Sun's surface.
It involves a very broad spectrum of emissions, requiring an energy release of up to 6 × 1025joules of energy (roughly the equivalent of 160,000,000,000 megatons of TNT, over 25,000 times more energy than released from the impact of Comet Shoemaker–Levy 9 with Jupiter).
Flares are often, but not always, accompanied by a spectacular coronal mass ejection. The flare ejects clouds of electrons, ions, and atoms through the corona of the sun into space. These clouds typically reach Earth a day or two after the event. The term is also used to refer to similar phenomena in other stars, where the term stellar flare applies.

Solar flares affect all layers of the solar atmosphere (photosphere, chromosphere, and corona), when the plasma medium is heated to tens of millions of Kelvin, while the cosmic-ray-like electrons, protons, and heavier ions are accelerated to near the speed of light. They produce radiation across the electromagnetic spectrum at all wavelengths, from radio waves to gamma rays, although most of the energy is spread over frequencies outside the visual range and for this reason the majority of the flares are not visible to the naked eye and must be observed with special instruments. Flares occur in active regions around sunspots, where intense magnetic fields penetrate the photosphere to link the corona to the solar interior.
Flares are powered by the sudden (timescales of minutes to tens of minutes) release of magnetic energy stored in the corona. The same energy releases may produce coronal mass ejections (CME), although the relation between CMEs and flares is still not well established.

Solar Max Double Peaked - The Solar Cycle - Science at NASA

Solar Max Double Peaked - The Solar Cycle - Science at NASA

Solar Max Double Peaked - The Solar Cycle - Science at NASA

The solar cycle or solar magnetic activity cycle is the nearly periodic 11-year change in the Sun's activity (including changes in the levels of solar radiation and ejection of solar material) and appearance (changes in the number and size of sunspots, flares, and other manifestations).
They have been observed (by changes in the sun's appearance and by changes seen on Earth, such as auroras) for centuries.
The changes on the sun cause effects in space, in the atmosphere, and on Earth's surface. While it is the dominant variable in solar activity, aperiodic fluctuations also occur.
Observational history
The solar cycle was discovered in 1843 by Samuel Heinrich Schwabe, who after 17 years of observations noticed a periodic variation in the average number of sunspots.[3] Rudolf Wolf compiled and studied these and other observations, reconstructing the cycle back to 1745, eventually pushing these reconstructions to the earliest observations of sunspots by Galileo and contemporaries in the early seventeenth century.
FollowingWolf's numbering scheme, the 1755–1766 cycle is traditionally numbered "1". Wolf created a standard sunspot number index, the Wolf index, which continues to be used today.
The period between 1645 and 1715, a time of few sunspots, is known as the Maunder minimum, after Edward Walter Maunder, who extensively researched this peculiar event, first noted by Gustav Spörer.
In the second half of the nineteenth century Richard Carrington and by Spörer independently noted the phenomena of sunspots appearing at different latitudes at different parts of the cycle.
The cycle's physical basis was elucidated by Hale and collaborators, who in 1908 showed that sunspots were strongly magnetized (the first detection of magnetic fields beyond the Earth). In 1919 they showed that the magnetic polarity of sunspot pairs:
Is constant throughout a cycle;
Is opposite across the equator throughout a cycle;
Reverses itself from one cycle to the next.
Hale's observations revealed that the complete magnetic cycle spans two solar cycles, or 22 years, before returning to its original state. However, because nearly all manifestations are insensitive to polarity, the "11-year solar cycle" remains the focus of research.
In 1961 the father-and-son team of Harold and Horace Babcock established that the solar cycle is a spatiotemporal magnetic process unfolding over the Sun as a whole. They observed that the solar surface is magnetized outside of sunspots; that this (weaker) magnetic field is to first order a dipole; and that this dipole undergoes polarity reversals with the same period as the sunspot cycle. Horace's Babcock model described the Sun's oscillatory magnetic field, with a quasi-steady periodicity of 22 years. It covered the oscillatory exchange of energy between poloidal and toroidal solar magnetic field ingredients. The two halves of the 22-year cycle are not identical, typically alternating cycles show higher (lower) sunspot counts (the "Gnevyshev–Ohl Rule".)

https://www.youtube.com/watch?v=SX0Ani8az18
Does the sun have the power to transform humankind?
In SOLAR (R)EVOLUTION, world-renowned German biophysicist Dieter Broers makes a compelling case, pointing to a wealth of scientific evidence that shows a remarkable correlation between increases in solar activity and advances in our creative, mental, and spiritual abilities.
We are in the midst of a dramatic rise in solar disturbances, which have the capability of disrupting the Earth’s geomagnetic field and, as a result, our global ecology. Broers, however, sees this not as an impending apocalypse but as the dawn of a new era.
Drawing on research from a variety of disciplines, he shows how erupting solar activity carries the potential to boost our brain capacity and expand our minds in ways we never imagined possible. Abilities now seen as extraordinary or supernatura - telepathy, extrasensory perception, and off-the-charts intelligence quotients - may soon become ordinary and natural and could very well help us solve the mounting global crises we are facing.
Without a doubt, the way we think, feel, relate, communicate, and experience reality has been changing dramatically in recent years, and Dieter Broers affirms those changes will ultimately culminate in a new form of consciousness and harmony on Earth. Humankind is going through an evolutionary leap, says Broers, and the process has already begun.

Does the sun have the power to transform humankind?
In SOLAR (R)EVOLUTION, world-renowned German biophysicist Dieter Broers makes a compelling case, pointing to a wealth of scientific evidence that shows a remarkable correlation between increases in solar activity and advances in our creative, mental, and spiritual abilities.
We are in the midst of a dramatic rise in solar disturbances, which have the capability of disrupting the Earth’s geomagnetic field and, as a result, our global ecology. Broers, however, sees this not as an impending ...

Prof. dr. Kees de Jager has been studying the Sun for most of his life as a professional astrophysicist. In the past few years he has focussed on the relation between solar activity and the Earth's climate.
In this talk, given on the 20th of may 2011, prof. de Jager presents the latest results of his work. One of the main conclusions is that the Sun does have a significant influence on the Earth's climate, in addition to the human induced effects.
The activity of the sun knows an 10-11 years cycle. During the period 2008 - 2010 the sun has been very quiet and the expected raise in activity started as late as 2011. Prof. de Jager expects a low maximum of the cycle that just started. It will be followed by a lengthy period of quietness, similar to the Maunder minimum of the 17th century.

Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun's atmosphere, the corona.
On July 19, 2012, an eruption occurred on the sun that produced all three. A moderately powerful solar flare exploded on the sun's lower right hand limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays -- a phenomenon known as coronal rain.
Over the course of the next day, hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, themselves, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, which highlights material at a temperature of about 50,000 Kelvin. This plasma acts as a tracer, helping scientists watch the dance of magnetic fields on the sun, outlining the fields as it slowly falls back to the solar surface.
The footage in this video was collected by the Solar Dynamics Observatory's AIA instrument. SDO collected one frame every 12 seconds, and the movie plays at 30 frames per second, so each second in this video corresponds to 6 minutes of real time. The video covers 12:30 a.m. EDT to 10:00 p.m. EDT on July 19, 2012.

It’s always shining, always ablaze with light and energy that drive weather, biology and more. In addition to keeping life alive on Earth, the sun also sends out a constant flow of particles called the solar wind, and it occasionally erupts with giant clouds of solar material, called coronal mass ejections, or explosions of X-rays called solar flares. These events can rattle our space environment out to the very edges of our solar system. In space, NASA’s Solar Dynamics Observatory, or SDO, keeps an eye on our nearest star 24/7. SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video, we experience SDO images of the sun in unprecedented detail. Presented in ultra-high definition, the video presents the dance of the ultra-hot material on our life-giving star in extraordinary detail, offering an intimate view of the grand forces of the solar system.

MAJOR X-CLASS SOLARFLARE (UPDATED): On Sept. 6th at 1202 UT, sunspot AR2673 unleashed a major X9.3-class solar flare--the strongest solar flare in more than a decade. X-rays and UV radiation from the blast ionized the top of Earth's atmosphere, causing a strong shortwave radio blackout over Europe, Africa and the Atlantic Ocean. The explosion also produced a coronal mass ejection (CME) with an Earth-directed component. The CME will probably reach our planet on Sept. 8th, bringing with it a chance of G2- or G3-class geomagnetic storms.

From NASA's Scientific VisualizationStudio. Solar flares may seem like far-away events, but they can damage satellites and even ground-based technologies and power grids. Every 11 years, as the sun reaches its maximum activity they become bigger and more common, and that increases the chances that one will significantly affect Earth.
So what are these solar eruptions? A solar flare is basically an explosion on the surface of the sun ranging from minutes to hours in length. Large flares can release enough energy to power the entire United States for a million years. Flares happen when the powerful magnetic fields in and around the sun reconnect. They're usually associated with active regions, often seen as sunspots, where the magnetic fields are strongest.
Flares are classified according to their strength. The smallest ones are B-class, followed by C, M and X, the largest. Similar to the Richter scale for earthquakes, each letter represents a ten-fold increase in energy output. So an X is 10 times an M and 100 times a C. Within each letter class, there is a finer scale from 1 to 9. C-class flares are too weak to noticeably affect Earth.
M-class flares can cause brief radio blackouts at the poles and minor radiation storms that might endanger astronauts. It's the X-class flares that are the real juggernauts. Although X is the last letter, there are flares more than 10 times the power of an X1, so X-class flares can go higher than 9. The most powerful flare on record was in 2003, during the last solar maximum. It was so powerful that it overloaded the sensors measuring it. They cut out at X17, and the flare was later estimated to be about X45.
A powerful X-class flare like that can create long lasting radiation storms, which can harm satellites, and even give airline passengers flying near the poles small radiation doses. X flares also have the potential to create global transmission problems and worldwide blackouts.
The seriousness of an X-class flare pointed at Earth is why NASA and NOAA constantly monitor the sun. NASA's Heliophysics fleet of spacecraft can now see the sun from every side and in many different wavelengths. This unprecedented coverage is enabling scientists to predict and detect space weather events like flares and CMEs with ever greater accuracy. With advance warning, governments and companies can take steps to protect their technological infrastructure, so that the worst scenarios will never happen.

The solar cycle or solar magnetic activity cycle is the nearly periodic 11-year change in the Sun's activity (including changes in the levels of solar radiation and ejection of solar material) and appearance (changes in the number and size of sunspots, flares, and other manifestations).
They have been observed (by changes in the sun's appearance and by changes seen on Earth, such as auroras) for centuries.
The changes on the sun cause effects in space, in the atmosphere, and on Earth's surface. While it is the dominant variable in solar activity, aperiodic fluctuations also occur.
Observational history
The solar cycle was discovered in 1843 by Samuel Heinrich Schwabe, who after 17 years of observations noticed a periodic variation in the average number of sunspots.[3] Rudolf Wolf compiled and studied these and other observations, reconstructing the cycle back to 1745, eventually pushing these reconstructions to the earliest observations of sunspots by Galileo and contemporaries in the early seventeenth century.
FollowingWolf's numbering scheme, the 1755–1766 cycle is traditionally numbered "1". Wolf created a standard sunspot number index, the Wolf index, which continues to be used today.
The period between 1645 and 1715, a time of few sunspots, is known as the Maunder minimum, after Edward Walter Maunder, who extensively researched this peculiar event, first noted by Gustav Spörer.
In the second half of the nineteenth century Richard Carrington and by Spörer independently noted the phenomena of sunspots appearing at different latitudes at different parts of the cycle.
The cycle's physical basis was elucidated by Hale and collaborators, who in 1908 showed that sunspots were strongly magnetized (the first detection of magnetic fields beyond the Earth). In 1919 they showed that the magnetic polarity of sunspot pairs:
Is constant throughout a cycle;
Is opposite across the equator throughout a cycle;
Reverses itself from one cycle to the next.
Hale's observations revealed that the complete magnetic cycle spans two solar cycles, or 22 years, before returning to its original state. However, because nearly all manifestations are insensitive to polarity, the "11-year solar cycle" remains the focus of research.
In 1961 the father-and-son team of Harold and Horace Babcock established that the solar cycle is a spatiotemporal magnetic process unfolding over the Sun as a whole. They observed that the solar surface is magnetized outside of sunspots; that this (weaker) magnetic field is to first order a dipole; and that this dipole undergoes polarity reversals with the same period as the sunspot cycle. Horace's Babcock model described the Sun's oscillatory magnetic field, with a quasi-steady periodicity of 22 years. It covered the oscillatory exchange of energy between poloidal and toroidal solar magnetic field ingredients. The two halves of the 22-year cycle are not identical, typically alternating cycles show higher (lower) sunspot counts (the "Gnevyshev–Ohl Rule".)

Does the sun have the power to transform humankind?
In SOLAR (R)EVOLUTION, world-renowned German biophysicist Dieter Broers makes a compelling case, pointing to a wealth of scientific evidence that shows a remarkable correlation between increases in solar activity and advances in our creative, mental, and spiritual abilities.
We are in the midst of a dramatic rise in solar disturbances, which have the capability of disrupting the Earth’s geomagnetic field and, as a result, our global ecology. Broers, however, sees this not as an impending apocalypse but as the dawn of a new era.
Drawing on research from a variety of disciplines, he shows how erupting solar activity carries the potential to boost our brain capacity and expand our minds in ways we never imagined possible. Abilities now seen as extraordinary or supernatura - telepathy, extrasensory perception, and off-the-charts intelligence quotients - may soon become ordinary and natural and could very well help us solve the mounting global crises we are facing.
Without a doubt, the way we think, feel, relate, communicate, and experience reality has been changing dramatically in recent years, and Dieter Broers affirms those changes will ultimately culminate in a new form of consciousness and harmony on Earth. Humankind is going through an evolutionary leap, says Broers, and the process has already begun.
Featuring: DIETER BROERS, RUPERT SHELDRAKE, MICHAEL PERSINGER, ERNST SENKOWSKI, MICHAEL KÖNIG, ILLOBRAND VON LUDWIGER, ELIZABETH RAUSCHER, ROLLIN MCCRATY, FRANZ HALBERG, GIULIANA CONFORTO, JJ & DESIREE HURTAK, FRANCINE BLAKE, and RICK STRASSMAN.

Solar Activity and Climate

Prof. dr. Kees de Jager has been studying the Sun for most of his life as a professional astrophysicist. In the past few years he has focussed on the relation between solar activity and the Earth's climate.
In this talk, given on the 20th of may 2011, prof. de Jager presents the latest results of his work. One of the main conclusions is that the Sun does have a significant influence on the Earth's climate, in addition to the human induced effects.
The activity of the sun knows an 10-11 years cycle. During the period 2008 - 2010 the sun has been very quiet and the expected raise in activity started as late as 2011. Prof. de Jager expects a low maximum of the cycle that just started. It will be followed by a lengthy period of quietness, similar to the Maunder minimum of the 17th centur...

Cosmic Journeys - Solar Superstorms

A fury is building on the surface of the Sun – high-velocity jets, a fiery tsunami wave that reaches 100,000 kilometers high, rising loops of electrified gas. What's driving these strange phenomena? How will they affect planet Earth? Find the answers as we venture into the seething interior of our star.

NASA | Thermonuclear Art – The Sun In Ultra-HD (4K)

It’s always shining, always ablaze with light and energy that drive weather, biology and more. In addition to keeping life alive on Earth, the sun also sends out a constant flow of particles called the solar wind, and it occasionally erupts with giant clouds of solar material, called coronal mass ejections, or explosions of X-rays called solar flares. These events can rattle our space environment out to the very edges of our solar system. In space, NASA’s Solar Dynamics Observatory, or SDO, keeps an eye on our nearest star 24/7. SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video, we experience SDO images of the sun in unprecedented detail. Presented in ultra-high definition, the video presents t...

Solar Flares - How the Sun Relaxes

Host: Edward DeLuca
Speaker: Lyndsay Flectcher (University of Glasgow)
The outer atmosphere of the Sun is a magnetically-dominated environment. The magnetic field determines the transport, storage and dissipation of energy, in fairly steady ways (coronal heating, solar wind acceleration) but also in abrupt and impulsive events called solar flares. Solar flares represent the rapid conversion of energy as the magnetically stressed corona relaxes, with magnetic energy going into plasma heating, the KE of accelerated particles and mass motions. Flares are now observed in exquisite detail with imaging and spectroscopy across the electromagnetic spectrum, allowing increasingly meaningful comparisons with detailed theory. In this talk I will give a general overview of recent flare observations a...

Prof. dr. Kees de Jager has been studying the Sun for most of his life as a professional astrophysicist. In the past few years he has focussed on the relation between solar activity and the Earth's climate.
In this talk, given on the 20th of may 2011, prof. de Jager presents the latest results of his work. One of the main conclusions is that the Sun does have a significant influence on the Earth's climate, in addition to the human induced effects.
The activity of the sun knows an 10-11 years cycle. During the period 2008 - 2010 the sun has been very quiet and the expected raise in activity started as late as 2011. Prof. de Jager expects a low maximum of the cycle that just started. It will be followed by a lengthy period of quietness, similar to the Maunder minimum of the 17th century.

Forget asteroids: Solar storm could cause apocalypse on Earth with just 12 hours warning
The government has alarmingly admitted it is woefully underprepared for a major solar storm which could cause plane crashes, train derailments, huge fires, mass power blackouts and satellite disruption.
A solar storm follows eruptions of mass and energy from the suns surface, including flares, sunspots, and coronal mass ejections which send huge amounts of X-rays and radiation towards Earth.
Solar storm can refer to: Solar flare, a large explosion in the suns atmosphere. Coronal mass ejection (CME), a massive burst of solar wind, sometimes associated with solar flares. Geomagnetic storm, the interaction of the Suns outburst with Earths magnetic field.
A coronal mass ejection (CME) is a massive burst of gas and magnetic field arising from the solar corona and being released into the solar wind.
Coronal mass ejections release huge quantities of matter and electromagnetic radiation into space above the suns surface, either near the corona (sometimes called a solar prominence), or farther into the planet system, or beyond (interplanetary CME). The ejected material is a plasma consisting primarily of electrons and protons. While solar flares are very fast, CMEs are relatively slow.
Near solar maxima, the Sun produces about three CMEs every day, whereas near solar minima, there is about one CME every five days.
When the ejection is directed towards Earth and reaches it as an interplanetary CME (ICME), the shock wave of the traveling mass of solar energetic particles causes a geomagnetic storm that may disrupt Earths magnetosphere, compressing it on the day side and extending the night-side magnetic tail. When the magnetosphere reconnects on the nightside, it releases power on the order of terawatt scale, which is directed back toward Earths upper atmosphere.
Solar energetic particles can cause particularly strong aurorae in large regions around Earths magnetic poles. These are also known as the Northern Lights (aurora borealis) in the northern hemisphere, and the Southern Lights (aurora australis) in the southern hemisphere. Coronal mass ejections, along with solar flares of other origin, can disrupt radio transmissions and cause damage to satellites and electrical transmission line facilities, resulting in potentially massive and long-lasting power outages.
Humans at high altitudes, as in airplanes or space stations, risk exposure to relatively intense cosmic rays. Cosmic rays are potentially lethal in high quantities. The energy absorbed by astronauts is not reduced by a typical spacecraft shield design and, if any protection is provided, it would result from changes in the microscopic inhomogeneity of the energy absorption events.

NASA | Fiery Looping Rain on the Sun

Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun's atmosphere, the corona.
On July 19, 2012, an eruption occurred on the sun that produced all three. A moderately powerful solar flare exploded on the sun's lower right hand limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays -- a phenomenon known as coronal rain.
Over the course of the next day, hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, themselves, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, which highlights material at a temperature of about 50,000 Kelvin. This plasma acts as a tracer, helping scientists watch the dance of magnetic fields on the sun, outlining the fields as it slowly falls back to the solar surface.
The footage in this video was collected by the Solar Dynamics Observatory's AIA instrument. SDO collected one frame every 12 seconds, and the movie plays at 30 frames per second, so each second in this video corresponds to 6 minutes of real time. The video covers 12:30 a.m. EDT to 10:00 p.m. EDT on July 19, 2012.

SOLAR ACTIVITY UPDATE: X9.3-Class Flare/EDCME: Sept. 7th, 2017.

MAJOR X-CLASS SOLARFLARE (UPDATED): On Sept. 6th at 1202 UT, sunspot AR2673 unleashed a major X9.3-class solar flare--the strongest solar flare in more than a decade. X-rays and UV radiation from the blast ionized the top of Earth's atmosphere, causing a strong shortwave radio blackout over Europe, Africa and the Atlantic Ocean. The explosion also produced a coronal mass ejection (CME) with an Earth-directed component. The CME will probably reach our planet on Sept. 8th, bringing with it a chance of G2- or G3-class geomagnetic storms.

Extreme Solar Flares

Watch this and other space videos at http://SpaceRip.com
From NASA's Scientific VisualizationStudio. Solar flares may seem like far-away events, but they can damage satellites and even ground-based technologies and power grids. Every 11 years, as the sun reaches its maximum activity they become bigger and more common, and that increases the chances that one will significantly affect Earth.
So what are these solar eruptions? A solar flare is basically an explosion on the surface of the sun ranging from minutes to hours in length. Large flares can release enough energy to power the entire United States for a million years. Flares happen when the powerful magnetic fields in and around the sun reconnect. They're usually associated with active regions, often seen as sunspots, where the magnetic fields are strongest.
Flares are classified according to their strength. The smallest ones are B-class, followed by C, M and X, the largest. Similar to the Richter scale for earthquakes, each letter represents a ten-fold increase in energy output. So an X is 10 times an M and 100 times a C. Within each letter class, there is a finer scale from 1 to 9. C-class flares are too weak to noticeably affect Earth.
M-class flares can cause brief radio blackouts at the poles and minor radiation storms that might endanger astronauts. It's the X-class flares that are the real juggernauts. Although X is the last letter, there are flares more than 10 times the power of an X1, so X-class flares can go higher than 9. The most powerful flare on record was in 2003, during the last solar maximum. It was so powerful that it overloaded the sensors measuring it. They cut out at X17, and the flare was later estimated to be about X45.
A powerful X-class flare like that can create long lasting radiation storms, which can harm satellites, and even give airline passengers flying near the poles small radiation doses. X flares also have the potential to create global transmission problems and worldwide blackouts.
The seriousness of an X-class flare pointed at Earth is why NASA and NOAA constantly monitor the sun. NASA's Heliophysics fleet of spacecraft can now see the sun from every side and in many different wavelengths. This unprecedented coverage is enabling scientists to predict and detect space weather events like flares and CMEs with ever greater accuracy. With advance warning, governments and companies can take steps to protect their technological infrastructure, so that the worst scenarios will never happen.

Solar Max Double Peaked - The Solar Cycle - Science at NASA

The solar cycle or solar magnetic activity cycle is the nearly periodic 11-year change in the Sun's activity (including changes in the levels of solar radiation and ejection of solar material) and appearance (changes in the number and size of sunspots, flares, and other manifestations).
They have been observed (by changes in the sun's appearance and by changes seen on Earth, such as auroras) for centuries.
The changes on the sun cause effects in space, in the atmosphere, and on Earth's surface. While it is the dominant variable in solar activity, aperiodic fluctuations also occur.
Observational history
The solar cycle was discovered in 1843 by Samuel Heinrich Schwabe, who after 17 years of observations noticed a periodic variation in the average number of sunspots.[3] Rudolf Wolf compiled and studied these and other observations, reconstructing the cycle back to 1745, eventually pushing these reconstructions to the earliest observations of sunspots by Galileo and contemporaries in the early seventeenth century.
FollowingWolf's numbering scheme, the 1755–1766 cycle is traditionally numbered "1". Wolf created a standard sunspot number index, the Wolf index, which continues to be used today.
The period between 1645 and 1715, a time of few sunspots, is known as the Maunder minimum, after Edward Walter Maunder, who extensively researched this peculiar event, first noted by Gustav Spörer.
In the second half of the nineteenth century Richard Carrington and by Spörer independently noted the phenomena of sunspots appearing at different latitudes at different parts of the cycle.
The cycle's physical basis was elucidated by Hale and collaborators, who in 1908 showed that sunspots were strongly magnetized (the first detection of magnetic fields beyond the Earth). In 1919 they showed that the magnetic polarity of sunspot pairs:
Is constant throughout a cycle;
Is opposite across the equator throughout a cycle;
Reverses itself from one cycle to the next.
Hale's observations revealed that the complete magnetic cycle spans two solar cycles, or 22 years, before returning to its original state. However, because nearly all manifestations are insensitive to polarity, the "11-year solar cycle" remains the focus of research.
In 1961 the father-and-son team of Harold and Horace Babcock established that the solar cycle is a spatiotemporal magnetic process unfolding over the Sun as a whole. They observed that the solar surface is magnetized outside of sunspots; that this (weaker) magnetic field is to first order a dipole; and that this dipole undergoes polarity reversals with the same period as the sunspot cycle. Horace's Babcock model described the Sun's oscillatory magnetic field, with a quasi-steady periodicity of 22 years. It covered the oscillatory exchange of energy between poloidal and toroidal solar magnetic field ingredients. The two halves of the 22-year cycle are not identical, typically alternating cycles show higher (lower) sunspot counts (the "Gnevyshev–Ohl Rule".)

Does the sun have the power to transform humankind?
In SOLAR (R)EVOLUTION, world-renowned German biophysicist Dieter Broers makes a compelling case, pointing to a wealth of scientific evidence that shows a remarkable correlation between increases in solar activity and advances in our creative, mental, and spiritual abilities.
We are in the midst of a dramatic rise in solar disturbances, which have the capability of disrupting the Earth’s geomagnetic field and, as a result, our global ecology. Broers, however, sees this not as an impending apocalypse but as the dawn of a new era.
Drawing on research from a variety of disciplines, he shows how erupting solar activity carries the potential to boost our brain capacity and expand our minds in ways we never imagined possible. Abilities now seen as extraordinary or supernatura - telepathy, extrasensory perception, and off-the-charts intelligence quotients - may soon become ordinary and natural and could very well help us solve the mounting global crises we are facing.
Without a doubt, the way we think, feel, relate, communicate, and experience reality has been changing dramatically in recent years, and Dieter Broers affirms those changes will ultimately culminate in a new form of consciousness and harmony on Earth. Humankind is going through an evolutionary leap, says Broers, and the process has already begun.

Solar Activity and Climate

Prof. dr. Kees de Jager has been studying the Sun for most of his life as a professional astrophysicist. In the past few years he has focussed on the relation between solar activity and the Earth's climate.
In this talk, given on the 20th of may 2011, prof. de Jager presents the latest results of his work. One of the main conclusions is that the Sun does have a significant influence on the Earth's climate, in addition to the human induced effects.
The activity of the sun knows an 10-11 years cycle. During the period 2008 - 2010 the sun has been very quiet and the expected raise in activity started as late as 2011. Prof. de Jager expects a low maximum of the cycle that just started. It will be followed by a lengthy period of quietness, similar to the Maunder minimum of the 17th century.

NASA | Thermonuclear Art – The Sun In Ultra-HD (4K)

It’s always shining, always ablaze with light and energy that drive weather, biology and more. In addition to keeping life alive on Earth, the sun also sends out a constant flow of particles called the solar wind, and it occasionally erupts with giant clouds of solar material, called coronal mass ejections, or explosions of X-rays called solar flares. These events can rattle our space environment out to the very edges of our solar system. In space, NASA’s Solar Dynamics Observatory, or SDO, keeps an eye on our nearest star 24/7. SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video, we experience SDO images of the sun in unprecedented detail. Presented in ultra-high definition, the video presents the dance of the ultra-hot material on our life-giving star in extraordinary detail, offering an intimate view of the grand forces of the solar system.

Solar Flares - How the Sun Relaxes

Host: Edward DeLuca
Speaker: Lyndsay Flectcher (University of Glasgow)
The outer atmosphere of the Sun is a magnetically-dominated environment. The magnetic field determines the transport, storage and dissipation of energy, in fairly steady ways (coronal heating, solar wind acceleration) but also in abrupt and impulsive events called solar flares. Solar flares represent the rapid conversion of energy as the magnetically stressed corona relaxes, with magnetic energy going into plasma heating, the KE of accelerated particles and mass motions. Flares are now observed in exquisite detail with imaging and spectroscopy across the electromagnetic spectrum, allowing increasingly meaningful comparisons with detailed theory. In this talk I will give a general overview of recent flare observations and the framework in which they are interpreted, before focusing on one aspect of flare physics, namely the need to rapidly transport energy through the corona and accelerate particles. I will also place our knowledge of solar flares in the context of what we are learning about stellar flares.

Forget asteroids: Solar storm could cause apocalypse on Earth with just 12 hours warning
The government has alarmingly admitted it is woefully underprepared for a major solar storm which could cause plane crashes, train derailments, huge fires, mass power blackouts and satellite disruption.
A solar storm follows eruptions of mass and energy from the suns surface, including flares, sunspots, and coronal mass ejections which send huge amounts of X-rays and radiation towards Earth.
Solar storm can refer to: Solar flare, a large explosion in the suns atmosphere. Coronal mass ejection (CME), a massive burst of solar wind, sometimes associated with solar flares. Geomagnetic storm, the interaction of the Suns outburst with Earths magnetic field.
A coronal mass ejection (CME) is a massive burst of gas and magnetic field arising from the solar corona and being released into the solar wind.
Coronal mass ejections release huge quantities of matter and electromagnetic radiation into space above the suns surface, either near the corona (sometimes called a solar prominence), or farther into the planet system, or beyond (interplanetary CME). The ejected material is a plasma consisting primarily of electrons and protons. While solar flares are very fast, CMEs are relatively slow.
Near solar maxima, the Sun produces about three CMEs every day, whereas near solar minima, there is about one CME every five days.
When the ejection is directed towards Earth and reaches it as an interplanetary CME (ICME), the shock wave of the traveling mass of solar energetic particles causes a geomagnetic storm that may disrupt Earths magnetosphere, compressing it on the day side and extending the night-side magnetic tail. When the magnetosphere reconnects on the nightside, it releases power on the order of terawatt scale, which is directed back toward Earths upper atmosphere.
Solar energetic particles can cause particularly strong aurorae in large regions around Earths magnetic poles. These are also known as the Northern Lights (aurora borealis) in the northern hemisphere, and the Southern Lights (aurora australis) in the southern hemisphere. Coronal mass ejections, along with solar flares of other origin, can disrupt radio transmissions and cause damage to satellites and electrical transmission line facilities, resulting in potentially massive and long-lasting power outages.
Humans at high altitudes, as in airplanes or space stations, risk exposure to relatively intense cosmic rays. Cosmic rays are potentially lethal in high quantities. The energy absorbed by astronauts is not reduced by a typical spacecraft shield design and, if any protection is provided, it would result from changes in the microscopic inhomogeneity of the energy absorption events.
